Method and network for providing access to an information network

摘要

An intelligent network for providing access to an information network ( 80 ) has a number of central office switches ( 64, 82 ). Each central office switch ( 64, 82 ) is capable of receiving a call to a centrex telephone number and transmitting a query. A service control point ( 70 ) is coupled to the central office switches ( 64, 82 ) by a SS7 signal link ( 66 ). The service control point receives the query and transmits a response to the central office switch ( 64, 82 ). A hub switch ( 75 ) is coupled to the central office switches ( 64, 82 ) and receives the call. The hub switch ( 75 ) contains a digital trunk service ( 76 ) that combines the call with a number of other calls to form a data stream. The data stream is then transmitted to an information network node ( 80 ).
